Selling The Product de End Of The Line

So they told you to play your part
synthetic beat without a heart
like dolls on strings, you'll be replaced
when they are bored of your faces
drawing board for a teenage dream
keep staying in the middle stream
well, how much might the product fetch?
where is the next wave to catch?

This is rock and it ain't buiss
I'm an old-fashioned idealist
And I'm so screwed up on this
